f7 TTORNEYS Patented Mar. 4, 1930 tirait RUDOLF VON FROMMER, OF BUDAPEST, HUNGARY CARTRIDGE GUIDE FOR REPEATING GUNS Application led August 14, 1928, Serial No. 299,627, and in Hungary August 24, 1927.

In my U. S. Patent No. 1,660,282 a cartridge guide for single-loading firearms, that is to say for non-repeating guns is described, comprising a spring pressed lever pivoted on the outside of the breech casing,

and having a head portion provided with a guiding surface and reaching through an opening 'provided in thc breech casing, the

said head portion guiding the cartridge 1o placed between the rear end of the barrel and the breech at the closing of the latter into the firing chamber. This mechanism is needed in firearms of such type in which the simple closing of the breech does not assure the correct introduction of the cartridge into the iiring chamber because the position occupied by the cartridge previous to the introduction thereof into the chamber differs so much from the position of the latter that the cartridge is not lifted to the height of the chamber at the closing of the breech bolt.

The present invention has for its object to provide a cartridge guide of such type which will make it possible to apply such cartridge guide in repeating guns also with substantial advantage and more especially in repeating guns provided with a magazine of the upward feed type. The same difficulties, which are confronted at the introduction of a cartridge in single loading firearms in consequence of the great difference of height, are also met in repeating guns of the upward feed type, especially if cartridges of small diameter are to be loaded into barrels of a considerable wall thickness. The cartridge guide according to the invention may render excellent services in such guns, too, if it is properly constructed.

For this purpose, the cartridge guide according to my U. S. Patent above referred to is so formed that its head portion which is provided with a guiding surface shall penetrate into the breech casing between the magazine and the rear end of the barrel, or the firing chamber.

In the accompanying drawing one form of the cartridge guide according to the invention is diagrammatically shown by way of example.

Fig. l is a vertical sectional view of the cartridge guide and the adjacent parts of the weapon, the breech bolt being closed.

Fig. 2 shows the same section, with open breech.

Fig. 3 is a cross sectional view taken on line III-III of Fig. 2.

According to the present invention the form of the cartridge guide here shown comprises, as in my U. S. Patent No. 1,660,282, lever 5 pivotally mounted adjacent to its rear end to swing on the axis 4, the front end or head portion 6 of the said lever being constantly extended up through the opening 7 of the breech casing 2 towards the interior of the latter by the spring 8 acting downwardly against its rear end. According to the present invention the lever 5 is of such a form that it clears the magazine l0, that is to say it enables the same to be freely inserted into and pulled out from the magazine chamber of the weapon. As will be evident from the drawings, the lever comprises longitudinal ly alined head and tail portions shown by the lead lines of the numerals 6 and 5, respectively, in Figures l and 2, and located at and beyond the opposite ends of the magazine l0, the head and tail being oined by a body portion laterally offset and located at one side of the magazine as shown in section in Figure 3, thereby providing a. channel between the head and tail conforming to the end and one side of the magazine, through which channel the magazine is inserted to extend into the brush opening. As in my pri or patent above referred to, the tail of t-he lever is formed with a socket therein to receive the spring S. For this purpose in the form shown in the drawing the lever 5 is arranged near the magazine adjacent to the right side thereof, the head portion 6 again returning towards the central axis of the fire arm in front of the magazine, so that the cartridge guiding surface 9 of the head portion 6 may guide the cartridge towards the firing chamber when the same is pushed forward by the breech bolt, in the same way as it has been described in my S. Patent No. 1,660,282. In consequence of the lever 5 being pivotally mounted and under the action of the spring 8 the head portion 6 yields at the closing of the breech bolt as in my previous patent above referred to and as shown in Fig. l.

Of course, the lever 5 may be arranged adjacent to both sides of the magazine, or, in

other words, the lever may be provided with a suitable longitudinal slot through which the magazine may penetrate, lor the pin 4 may be arranged on the front part of the casing 2 under the firing chamber or on the barrel, in which case a v counter image of the present arrangement is obtained and the clearing of the magazine becomes superfluous.

Having described my invention, I declare that what I olaimis: Y

l. In a ymagazine fire arm, a breech casing, a breech movable in said casing, an elongated opening in the base of said casing, a cartridge magazine insertible in sai'd opening from beneath the casing, a lever pivotally mounted on the under side of said casing adjacent its tail end and adjacent the rear end of said breech casing opening, said lever having a head portion positioned to enter the forward end of said opening and having an upwardly sloping cartridge guiding face, said head and tail portions being positioned'at and beyond the opposite ends of said magazine and being connected by a laterally offset body portion Y positioned at andoutwardly of one `side of said magazine and providing with said head and tail portions a channel through which the upper end of said magazine is freely insertible to extend into said breech casing opening, and a spring acting downwardly upon the tail portion of said lever and nor` mally maintaining its head portion extended upwardly in said breech opening in advance Of said cartridge magazine.

2. In a magazine fire arm, a breech casing, a breech movable in said easing, an elongated opening in the base of said casing, a cartridge magazine insertible in said opening from beneath the casing, a lever pivotally mounted on the underside of said casing having a head portion positioned to enter the forward end of said opening and provided with an upwardly sloping cartridge guiding fase andV having a tail portion underlying said casing rearwardly of said opening, said head andtail portions being spaced and connected by an intel-mediate body portion providing with said head and tail portions a channel through which the upper endof the cartridge magazinel is freely insertible to extend into said breech opening, said intermediate body portion being formed to clear the endswof the magazine and being laterally offset to clear the opposite sides thereof, and a spring acting against said lever "normally to maintain its head portion extended upwardly in saidV breech opening in advance of Vsaid cartridge magazine.

In testimony whereof I have alii-Xed my signature. Y RUDOLF voN FROMMER.`
